The present invention refers to a method for the production of haloalkane sulfonic acid, in which SOand an haloalkane are contacted with each other in the presence of a solvent, said solvent does constitute a superacid and the combination of said solvent with one or more of the reactants also gives rise to a superacid.

Process for the preparation of haloalkanesulfonic acids from sulfur trioxide and a haloalkane at superacidic conditions

The present invention relates to a method for recycling and/or disposal of halocarbons, particularly fluorinated alkanes, such as trifluoromethane, by reacting said halocarbons with sulfur trioxide, particularly to form halide sulfonic acids and sulfur dioxide.

Method for the recycling or disposal of halocarbons

The present invention relates to a process for preparing haloalkanesulfonic acids from sulfur trioxide and a haloalkane, particularly to a process for preparing trifluoromethane sulfonic acid from sulfur trioxide and trifluoromethane.

Process for the preparation of haloalkanesulfonic acids from sulfur trioxide and a haloalkane

The present invention relates to novel uses of stable inorganic peroxoacids as catalysts in the preparation of alkanesulfonic acids from alkanes and sulfur trioxide, methods for the production of alkanesulfonic acids employing said catalysts as well as reaction mixtures comprising said catalysts. The invention particularly relates to the production of methanesulfonic acid from methane and sulfur trioxide employing stable inorganic peroxoacids as catalysts.

Catalysts for the synthesis of alkanesulfonic acids

The present invention relates to a method for the purification of alkanes, especially methane, wherein an alkane comprising impurities, especially methane, is reacted with an active compound, optionally in the presence of sulfur trioxide, whereby the impurities are removed. The present invention furthermore relates to the use of the active compound and sulfur trioxide in the purification of alkanes, especially methane.

Method for the purification of alkanes

A compound of the formula (I)ALK&#x2014;SO&#x2014;O&#x2014;O&#x2014;SOOX,

Initiator for preparing alkanesulfonic acids from alkane and oleum

The present invention relates to an alkane-sulfonation process using alkane and sulfur trioxide, especially pure sulfur trioxide (100%) under solvent-free conditions in the presence of an initiator. It further relates to the use of a precursor which forms 'in-situ' an initiator for manufacturing of alkanesulfonic acids, especially methanesulfonic acids.

Solvent-free alkane sulfonation

A compound of the formula:CH&#x2014;SO&#x2014;O&#x2014;O&#x2014;SOOH.

A process for the preparation of a polymer nanoparticle by a photoinduced emulsion polymerization includes preparing an emulsion comprising at least one surfactant, a dispersed phase and a continuous phase. The dispersed phase comprises at least one polymerizable monomer and the continuous phase comprises water and at least one photoinitiator. The at least one polymerizable monomer is polymerized by exposing the emulsion to an electromagnetic radiation having a wavelength so as to induce a generation of radicals from the at least one photoinitiator. The at least one photoinitiator is selected from at least one compound of formula (I) 

Polymer nanoparticles

A process for preparing alkanesulfonic acids from sulfur trioxide and an alkane, wherein sulfur trioxide, the alkane and dialkylsulfonoyi peroxide (DASP) react as components, characterized in that the following steps are performed: a) sulfur trioxide is charged in a high-pressure reactor in a condensed phase; b) a temperature of at least 25&#xb0; C. is set; c) the gaseous alkane is introduced to the high-pressure reactor until a pressure of at least 10 bar is reached; d) dialkylsulfonoyi peroxide (DASP) is added; and e) after a duration of at least 5 hours, the produced alkanesulfonic acid is withdrawn.

Process for preparing alkanesulfonic acids from sulfur trioxide and an alkane

The invention pertains to an oligomer or polymer substituted by one or more bisacylphosphine oxide moieties, characterized in that said bisacylphosphine oxide moiety is linked via the phosphorous atom, optionally via a spacer group, to the oligomer or polymer backbone; as well as to specifically functionalized bisacylphosphine oxides, suitable to prepare said polymers or oligomers.
